Investment Property Tax Explained

Rental Income Is Taxable

Every dollar you receive in rent is assessable income in the eyes of the ATO. It gets added to your total taxable income (alongside your salary, business income, dividends, and any other earnings) and taxed at your marginal rate.

This is worth understanding clearly before you buy. If you earn $100,000 in salary and receive $25,000 in gross rental income, your total assessable income is $125,000. Without deductions, you're being taxed at the 37 cent rate on every dollar above $135,000.

Deductions are what change that picture significantly.

Tax Deductions Every Property Investor Should Be Claiming

Australian tax law allows investors to claim a wide range of property expenses as deductions against their rental income. These deductions reduce your taxable income and in many cases transform the financial performance of an investment property.

1. Interest on your investment loan

The interest component of your mortgage repayments is fully tax deductible. The principal repayment is not. This is one of the most significant deductions available to investors and one reason why interest-only loan periods are a common strategy.

2. Property management fees

If you use a property manager, their fees and commissions are fully deductible. This includes letting fees, management fees, and any charges for lease renewals.

3. Repairs and maintenance

Costs associated with keeping the property in its current condition are deductible in the year they're incurred. This includes fixing a broken appliance, repainting a room, or repairing a fence. It's important to distinguish repairs from improvements.

4. Insurance

Landlord insurance, building insurance, and contents insurance on an investment property are all deductible expenses.

5. Council rates and land tax

Council rates are payable by the property owner and are fully deductible for periods when the property is rented. Land tax, where it applies, is also deductible. Both are expenses investors regularly overlook at tax time.

6. Body corporate fees

For apartment and unit owners, body corporate fees and strata levies are deductible expenses. Given that these can run to several thousand dollars per year, they represent a meaningful deduction that should always be claimed.

7. Borrowing costs

Loan establishment fees, mortgage broker fees, lenders mortgage insurance, and title search fees are all deductible, though borrowing costs above $100 are typically spread across five years rather than claimed in full in year one.

8. Depreciation

This is the most underutilised deduction in property investment and the one that makes the biggest difference to after-tax returns.

Depreciation covers the wear and tear of the property over time across two categories:

• Capital works: the structural elements of the building including walls, roof, flooring, and driveways. Claimed at 2.5% per year over 40 years on construction costs.
• Plant and equipment:  the fixtures and fittings including appliances, carpets, air conditioning units, hot water systems, and blinds. 

A quantity surveyor's depreciation schedule unlocks these deductions in full. For newer properties especially, depreciation can generate tens of thousands of dollars in non-cash deductions annually, reducing your taxable income without requiring any additional out-of-pocket expense.

Negative Gearing Explained

A property is negatively geared when the total expenses of owning it exceed the rental income it generates, producing a net loss.

That net loss can be offset against your other taxable income, reducing your overall tax bill. This is what makes negative gearing one of Australia's most commonly used investment strategies.

Here's a simple example:

• Annual rental income: $28,000
• Annual expenses (interest, rates, management, insurance): $38,000
• Net loss: $10,000
• If your marginal tax rate is 37%, that $10,000 loss saves you $3,700 in tax

The tax saving is real, but it's important to understand what negative gearing actually is. It's a tax reduction strategy, not a profit strategy. You're still losing money on a cash flow basis. The investment case relies on capital growth over time being sufficient to more than offset those annual losses.

Negative gearing works best when paired with strong long-term capital growth in a supply-constrained market. Without growth, you're simply accumulating losses.

‍

Positive Gearing and Tax

A positively geared property generates more rental income than it costs to hold. The profit is added to your taxable income and taxed at your marginal rate.

While this increases your tax bill in the short term, positive cash flow provides the income buffer that allows investors to hold multiple properties simultaneously and weather periods of rising rates or unexpected expenses. For investors focused on portfolio scalability, positive cash flow is what keeps you in the game long enough for capital growth to compound.

‍

Capital Gains Tax When You Sell

When you sell an investment property for more than you paid for it, the profit is subject to capital gains tax. That profit is added to your assessable income in the year of sale, which can significantly increase your tax liability if you're not prepared.

Here’s what you should know:

The 50% CGT discount

If you've held the property for more than 12 months, only 50% of the capital gain is included in your assessable income. A $300,000 gain becomes $150,000 of taxable income. This concession rewards long-term holding and is one of the strongest tax advantages available to Australian property investors.

The six-year rule

If you move out of your primary place of residence and rent it out, you may be able to treat it as your main residence for CGT purposes for up to six years. This can result in a full CGT exemption on the eventual sale, subject to conditions. It's one of the most powerful and least understood concessions in Australian property tax law.

Timing your sale

Because capital gains are added to your income in the year of sale, timing matters. Selling in a year where your other income is lower for example, after leaving full-time employment can reduce the rate at which your gain is taxed.

‍

The Importance of Good Record Keeping

The ATO requires property investors to keep records of all rental income and deductible expenses for a minimum of five years. This includes:

• Rental statements from your property manager
• Receipts for all repairs, maintenance, and expenses
• Loan statements showing interest charges
• Insurance documents
• Depreciation schedules
• Purchase and sale contracts

You cannot claim a deduction you cannot substantiate. Digital record keeping from day one makes this straightforward and protects you in the event of an audit.

‍

The Bottom Line

Investment property tax in Australia is not something to manage reactively. The investors who get the best outcomes are the ones who understand the rules before they buy, structure their purchases correctly from the start, and claim every legitimate deduction available to them.

Tax won't change what you buy, but it changes how much you actually keep.
